Study Notes
Coastal Geography and Erosion Principles
- Coastal Erosion via Chemical Action: Erosion occurs when sea water dissolves minerals in rock due to the acidic nature of water, leading to the gradual breakdown of coastal formations.
- Prevailing Wind Direction: The most common wind direction impacting coastal processes is known as the prevailing wind.
- Coastal Accumulations: A long, narrow accumulation of sand and shingle that extends from the coastline is referred to as a spit.
- Weathering of Rocks: The breakdown of rocks at the Earth's surface, influenced by environmental factors, is known as weathering.
- Longshore Drift Mechanism: Gradual movement of sediment along a coast occurs as waves approach the shore at an angle, a process termed longshore drift.
- Hydraulic Action Erosion: A form of coastal erosion occurs when water traps air in rock cracks, and the force of waves can create pressure that leads to rock cracking and erosion.
- Formation of Coastal Features: A coastal feature known as an arch is formed when waves erode through a headland, creating an opening.
- Coastal Protection Structures: A seawall is a concrete wall constructed to protect coastlines from erosion and mitigate damage from wave activity.
- Cliff Erosion Features: The term for a hollow in a cliff, created by the erosion action of waves enlarging a crack, is known as a cave.
- Deposition Process: The process through which waves deposit materials on beaches, contributing to beach formation, is called deposition.
- Backwash Dominance: Powerful waves that have more backwash than swash are responsible for significant erosion of beaches.
- Beach Nourishment: The act of adding fresh sand to a beach to compensate for erosion loss is referred to as beach nourishment.
